All the upper test writing disk are same. From the upper result, if i use DRBD to test, the performance is 39 MB/s; while if i do not use, the performance is about 95M/s.

3. My question is: -) this write performance decays so large is normal or not? I had read the following from the DRBD website: "15.1. Hardware considerations: .... A single, reasonably recent, SCSI or SAS disk will typically allow streaming writes of roughly 40MB/s to the single disk." But this is very slow.

-ï¼‰if this is not normal, how can i turn this? is the config file something not correct?
